Description:
------------
When a NUMERIC or DECIMAL field with precision of 0 has a value of 0, when fetching data, an empty string is returned instead of zero.

According to CVS, it's still in the latest PHP4 version, but  the code has been changed in PHP5.

Here's the patch:

Reproduce code:
---------------
[Connect to database, then:]
  $query = "SELECT numeric_field FROM test_table WHERE numeric_field = 0";
  $rs = ibase_query($linkID, $query);
  $obj = ibase_fetch_object($rs);
  print("'$obj->NUMERIC_FIELD'");

Expected result:
----------------
'0' should be printed

Actual result:
--------------
'' is printed
